Time to refresh your Bissell air purifier? Grab this convenient 2-pack of genuine H13 True HEPA replacement filters (part number 3389). They're made specifically for the Bissell MYair+ and MYair HUB models 2905A and 3179A. (Quick heads up: double-check your model – these do NOT fit the 2780A, 2780, 27809, or 3139A models). Each filter is a 3-in-1 system. It's got a pre-filter that catches the bigger stuff like dust and pet hair, a True HEPA layer that traps tiny particles like pollen and smoke (down to 0.3 microns!), and an activated carbon layer to help tackle household odors from cooking, pets, you name it. Swapping them out is a breeze – no tools needed. Just pop the old one out and the new one in. Bissell recommends replacing these every 4 to 6 months, depending on how much you run your purifier and your air quality. Having a two-pack means you're set for almost a year, which is super handy. They're made with quality materials, including FSC-certified paper. Keep your air clean and your purifier running at its best with these reliable replacement filters. Your lungs (and your purifier) will thank you!
